Procedure

398.7 parts of 1-methoxy-2-propanol were charged in a reaction vessel and heated under a nitrogen flow so that the internal temperature of the vessel was 70° C. Then a solution in which 12.9 parts of methacrylic acid, 75.7 parts of allyl methacrylate (composition ratio of these methacrylic acid and ester thereof was 20:80 in molar ratio), and 3.73 parts of V-65 (2,2′-azobis-(2,4′-dimethylvaleronitrile), manufactured by Wako Pure Chemical Co.) were dissolved in 398.7 parts of 1-methoxy-2-propanol was dropwise added into the vessel over a period of 2.5 hours. The mixture was agitated further for 2 hours under heating at 70° C. The obtained reaction liquid was poured into 4000 parts of water, and the resulting solid was separated by filtration and dried under vacuum to obtain a methacrylic acid/allyl methacrylate copolymer (copolymer 6). The weight-average molecular weight of the copolymer was 36,000 (converted as polystyrene).
